Biobased lignin gels offer sustainable alternative for hair conditioning

Researchers at Stockholm University have developed a fully biobased hair conditioner using lignin gel emulsions, offering a sustainable and environmentally friendly alternative to conventional haircare products.

Hair conditioners typically contain 20–30 ingredients, many derived from petroleum and oleochemicals, raising concerns about sustainability and environmental impact.

A study published in Science Advances, demonstrates that micellar lignin gels can effectively stabilize emulsions with natural oils, reducing the need for synthetic surfactants and complex stabilizers commonly used in commercial formulations.

The research team, led by Mika Sipponen at Stockholm University, sought to explore lignin, a common and renewable component in wood biomass, as a multifunctional component for hair conditioning.

"Our findings highlight lignin's potential as a stabilizer in oil-in-water emulsions, enabling a more natural and sustainable approach to hair conditioning," says Sipponen.
